Tape supportingspools 71 are rot.;'i;ably supported in proper tening rolls from, theguide rolls 73, also holding the tapes down upon said moistenin rolls.The tapes pass from the guide r0 ls upward through tape openings 75"formed through the restv 61, and in the side of the block 76, back ofthe shoe 62, for the side of the machine,

said openway 34c, and being located back of the die plate 38, for thetape on the right-hand side of the machine. The shafts of themoisintermeshing gears 78 sehas'a ratchet 79 eeured thereto and engaged-"by a pawl 80 pivotally mounted on a pawl actuating lever 81 rotatablysup orted' on said shaft and connected by a r0 82 with v a lever 83pivotally supported on the bed,

. a curved bar 84: extending around the shaft 28 and pivotally securedto the lever 83,

. conneeting said lever c) wlth an actuating rod .85. having its lowerend forked to straddle I the shaft 28 and bearing a roll 86 riding incontact with a cam 87 secured to the shaft 28' and by means of whichsaid rod is reciprocated, thereby imparting a step by step moisteningrolls through connection justdescribed.

Apost 88 rises from the bed 11, this post being curved to locate aholder disk 89, r0-

tatably supported at its upper end, over a rivet feed for supplyingrivets to the mech anism. A holder 90 is secured to the disk in'the formof a Wire upon which rivets 91 are placed. These. rivets are ofa formcommonly used on encentral tubular portion arms 93 as shown in Fig. 5,arms are adapted to be passed 92 with flexible v.velop and then ,bentbackward upon themthe envelop in ul arportion of the rivets located inthe bracket 97. The

The lower part disk 89- may berotated, as by means of a handle 95, toplace the holder in a. position diametrically opposite to that shown inFig. 2, in which. position the holder may be loaded. After it has beenloaded, and before it is placed in position to feed, an

aliner 96, pivotally mounted on the post 88 is employed to aline the r"et arms so that they will pass into the gui 94 when the holder isrotated to the feed position shown in Fig. 2. This aliner consists of anarm having a groove to receive and fit upon the central hub portion ofthe rivets, this arm being pivotally mounted on the post, as clearlyshown in Fig. 8, it being of a length to engage all of the rivets on theholder when swung upwardly from the position shown in Fig. 1, abovedescribed.

The bracket 97.1s

thus alining the rivets as secured to the block 76, rising therefrom tosupport a rivet carrier rotatably supported thereby. in branches 100,This rivet carrienconsists of a disk 101 having a 103 is secured, thedisk 101 being also pro vided with journals 104C resting in bearings inthe branches 100. A series of recesses 105 hub 102 on which an annulardisk are formed radially within the carrier, onehalf of each recessbeing formed in the disk 101 and the other half in the annular disk103', the latter having lugs 107 from rivet holding fingers 108 areseated upon a spring 109 located in a' recess .in the hub, as clearlyshown in Fig, 6 of the drawings. A track 110 is secured at its lower endin a groove in the block 76, this track curving over the bracket 97, asclearly shown in Fig, 5 and having a cam plate 111 secured at its upperend, and located in position to be engaged by the lugslO'Zto move therivet holding fingers radially inward in the cal rier and permit them topass under the end of the track 110, said lugs, however,-being releasedfrom said cam and allowing the fingers to spring outward and enter theopening in the bottom rivet supported on the holder 90,. as shown inFig. 5, from which position, in the rotation of thecarrier, the rivetsare carried downwardly through -a runway 112 consisting ofa grooveformed in the 'track 110. This groove is closed by a an extension fromthe guide 971, this cover holding the rivets within the groove or run'-'way'as they travel downward therein. The movement of the fingerswithdraws them from the openings in the rivets at a certain point, fromwhich the rivets fall on to a rivet rest 114 located at the lower end ofthe runway, the rivet being thus held in position for action of therivetslots 106 within'which located. The rivet holding fingers are eachif desired, constitute in a curved path mg punch 53 operating through anopening 115 in the track 110 and against the die 98.

of the runway 112 is closed by a gate 116 mounted on a latch 117pivotally supported on the block 7 6 and having a cam 118 located in thepath of movement of the end of the plunger 52. This gate has an opening119 in its edge to receive the hollow hub of the rivet, and the cam 118is so formed that, as the riveting plunger 52 moves forward, it operatesto move the gate backward at the proper time to allow the rivet to becarried by the pin 54 against the die 98, a spring 160 returning thelatch 117 to its normal position, as shown in Fig. 4. A ratchet wheel120 is secured to one of the journals of the carrier and is actuated bya pawl 121 supported on a pawl lever 122 mounted onthe journal andconnected by a rod 123 with an actuating arm 124 mounted on the slide47. A pin from the arm 124 is located in a. slot 125 in the rod, and aspring 126 connects the arm 124 with the lever 122 independently of saidrod so that, should any obstruction present itself to movement of thecarrier to feedirivets along the runway, the spring will permit the arm124 to move and thus avoid injury of parts, the engagement of the pinwith the slot posi- .tively moving the pawl to reengage the ratchet.

A tape feed support 127 rises from the bed 11 and has a foot 128 bymeans of which it is secured to the bed, this support having branches129-13l) at its upper end in which a tape feed shaft-131 is journaled. Atape feed operatingv lever 132 is rotatably mounted on the shaft and hasa pawl engaging a ratchet 133 secured to the shaft.

The lever 132 may be formed intoa handle 134, and it is connected withthe actuating rod 85 whereby the tape feed is actuated by means of thecam 87 on the shaft 28, from whichit will be seen that the feed of thetape at the moistening device and at the upper part of the machine issimultaneous and from the same source. A feed wheel 135 is secured tothe shaft 131, this wheel having teeth to engage with teeth on a feedwheel 136 loosely mounted on its shaft and also journaled in thebranches 129-130, the

i teeth on one wheel pressing the paper tape with the other.

into the space between the teeth on the other wheel; The shaft of thefeed wheel 136 has cams '13? arranged to engage flanges 138 .projectingfrom the branches of the support 127. This shaft is mounted in boxes 139located in slots in the branches and pressed towardthe feed wheel 135 bysprings 140 seated upon the boxes and thrusting against a cap 141secured to said branches. Ahandle 142 is secured to one of the cams orto Y the shaft, and by means of this handle, when the cams are caused toengage the flanges at their highest portions, the teeth of the feedwheels will be forced from engagement each Grooves 143 are formed in thefeed wheels in which guides 144 extend,

regular feedconsists of a main feed wheel 145 mounted on a bracket 146extending from the support 127, said main feed wheel having studs 147arranged to engage the openings in the paper tape made by cutting thewashers therefrom, each succeeding stud engaging the succeeding openingsin the paper tape and thus imparting a regular step by step feedmovement thereto. This main feed wheel is rotated as by means of anintermediate gear 148 mounted on a stud on said bracket, said gearmeshing with a pinion 149 formed, in the construction herein shown, as apart of the feed wheel 135, said intermediate gear also meshing with agear 150 mounted to drive the main feed wheel 145.

The operation of the device is as follows: It will be understood that inthe first few operations of the machine the tapes 72 are engaged by thefeed wheels 135-136 that draw upon the tape until a sufficient length isobtained to engage the studs 147 of the main feed wheel 145. after whichthe handle 142 is operated to dis ngage the feed wheel 136 from the feedwheel 135, by engagement of the cams 137 with theflanges 138.

The parts being in the positions shown in the figures of the drawings anenvelop is placed upon the shoe 62 resting with its edge upon the rest61 and with the end of the flap against the stop 63. Pressure upon thetreadle 24, through the connecting mechanism, disengagcs the startingand stopping pin 21 from the cam 19 and the spring 18,

place during a single rotation of the shaft 12, the stop 20 striking thepin 21.

The rotation of the shafts 28 and 29, through the intermeshing gears andconnections, simultaneously moves the perforating and supportin slide 33and the plunger sup porting slide 4 toward each other, in whichoperation the supporting plunger 3 5 1s moped through the opening 40 andagainst This rotates the driving. 1

, point and held the rivet in place. The latter being now free to bemoved forward is carried by the pin 5% against the die 98, the pinstriking the die and retreating into the riveting punch'53 in the rivetsecuring plunger 52. The latter now engages the rivet, forces it throughthe back or" the envelop and heads it on the die 98, securing the rivetin place. On the return movement the spring 56 will forcethe rivetsupporting pin 54= into the position shown in the drawings and thespring. (not shown) will return the latch 11? to the position shown,placing the gate in position to cover the runway to retain the nextrivet which shall pass down the;runway in positioiron the stop 11%. Inthis movement of the plunger supporting slide 47 the washer formingplunger 49 is carried forward, engaging the tape 72 in the tape opening75 on the left-hand side of the shoe 6:2, cutting a round disk -fromsaid tape by the action of the die opening 64, which disk is carriedthrough the opening 64 against the flap of the envelop within the Vgroove 39, the plunger 49 coming to rest with said disk lying againstsaid flap.

The movement of the perforating and sup porting slide 33 abovedescribed, moves the washer forming plunger 36 simultaneously with theplunger 49, the end of the plunger 36 engaging the tape in the opening(5 back of the die plate 38 and in connection with the die opening. 37,forming another disk from said tape, carrying said disk through theopening 37 and against theopposite side of the flap of the envelop fromthat against which the disk first above described is brought to rest. Inthis operation the perforating plunger all is also carried forward bymeans of the eccentric 46,:the plunger 11 reaching its forward positionjust after the slide 33 has reached its forward position. The slightdwell in the movement of the slides 33 and i7 caused by the eccentrics14 and 5 passing their centers is made use of for the operation of theplunger 4-1 which, during such dwell, passes through the two disks andthe envelo flap and in connection with the die opening 51 intheplungel-e9. produces a hole, thus completing the formation of thewashers, the piece taken out from the disks and the envelop flap passinginto'the opening 50 in the 'die 19, and eventually, by the successivelocation of the pieces within said opening, out through the opening inthe cap 57 The pressure of the diesat the end of the plungers 36 and 49will cause the washers, which have been produced from the tapes havingone side containing an adhesive moistened, to be firmly afiixed to theopposite side of the envelop.

At the time of starting the operation of the machine, as abovedescribed, the end of a finger 108. will be located in the bottom riveton the holder 90. The pawl 121 will, through the operation of theactuating arm 12% on the slide 4:7 and the connecting parts, rotate therivet carrier a one step movement,removing the bottom rivet, and passingit along the runway, and in a further movement of the carrier the rivetwill be located in' position so that the pin will pass out of theopening in the rivet and allow it to drop on to the stop 114. As onerivet is being removed from the holder 90, the lug 107 on the nextsucceeding plunger engages the cam plate 111, drawing the fingerradially inward so that-it may pass under the end of the track 110, andjust as soon as the lug disengages from said cam plate the finger snapsoutwardly into the b-pening in the rivet. 1

The rotation of the cam 87 by the shaft 28 through-the actuating rod 85and lever 83 and connecting parts, will simultaneously operate theratchet feed to impart a step by step movement to' the moistening rolls70 and to the main feed Wheel 1145, thus imparting a step by'stepmovement to the paper tapes which, being passed through the water orlike moistening material within the boxes 69, are properly moistened tobe aliixed to the envelop flap hereinabove described.

ln placing the rivet-s upon the holder 90, the handle 95 is operated torotate the holder disk 89, thus placing the holder 90 in a di.ametrically opposite positionfrom that shown in the figures, in whichposition, by means of a loader or otherwise, the rivets are placed uponthe holder. The aliner 96- is now swung upwardly projecting the hubs-92of the rivets into the groove in the aliner, thus bringing all of thearms 93 into alinement, after which, the aliner being moved to itsnormal position, as shown in Fig. 1, the holder is returned to'itsnormalposition, as shown in Fig. 2,. and the arms of the rivets beingthus alined will properly enter the groove in the guide 94.,

It will be understood that if it is desired to affix a Washer to oneside of the envelop flap only, this operation may take place simply byomitting a paper tape in one of the openings 75 on that side of the flapto '125 which it is desired'th'e washer shall npt be ailiXQd. r it I I il I While I haveshoivn'and described herein a form of mechanism employedby mefor effecting the desireda'esults, it will be understruction hereinshown and described.

The holder disk 89 is yieldingly held in different positions, andespecially in its feeding position by means of a spring seated pin 152and having aibeveled end engaging recess 153 to resiliently hold thedisk. By application of some force to the handle 95 the disk may bedisengaged and moved to a different position.
